4 Die In Fiery "Mud-Bogging" Accident

A sport utility vehicle speeding down a muddy road slammed into trees and exploded, killing four people, including two children, and injuring two others, authorities said.

Investigators believe alcohol, recent rain and reckless driving may have been factors in Friday night's crash of the Ford Bronco, which burned completely, state Trooper J.T. McMillan said.

"They were out there, playing around, mud-bogging on the dirt road," McMillan said. "They got stuck in the dirt and were pulled out by a dump truck. They sped off down the road and the driver struck two trees."

Mud bogging is an off-road motor sport in which drivers try to go as far as possible through a mud hole without bogging down.

The SUV was traveling around 70 mph at impact, and the occupants weren't wearing seat belts, he said.
